Embodiment Construction
[0033] The present invention will be described in detail below in conjunction with the drawings. The enumerated embodiments can enable those skilled in the art to better understand the present invention, but do not limit the present invention in any form.
[0034] Such as Figure 1-5 As shown, a transverse joint grouting pipeline of a concrete arch dam or a gravity arch dam is improved on the basis of the existing concrete dam transverse joint grouting technology, retaining the grout inlet pipe 11, the grout return pipe 13 and the grouting pipes required for grouting. Exhaust pipe 5, exhaust groove 6, exhaust pulp box 4 and spare pipeline etc. The standby pipeline is the same group of grout inlet and return pipes as the main grouting pipeline. Since the inlet and return grout pipes are buried in the concrete, one more set should be buried to ensure the smooth progress of the construction. The slurry inlet pipe, the slurry return pipe and the spare pipeline are arranged on the...
